Suppression of the call number display

The display of the call number to the called party can be suppressed (CLIR). CLIR
can be permanently activated or deactivated for each user in the Configuration
Manager. Each user can also use a */# function code to activate or deactivate CLIR
either permanently or only temporarily for a single call.

Detailed description of temporary CLIR

CLIR is activated temporarily using *31 before dialling an external call number. If
CLIR is already permanently activated, it can be deactivated temporarily using #31
before dialling. The permanent CLIR settings are restored once the call is comple-
ted.
Scope

network interfaces with the DSS1 protocol.
Notes:

i.e. the call number is displayed to the called party.
– Depending on the network provider and service provider it may be
necessary to subscribe to CLIR.
